A block of mass, 578 g is pushed against the spring by spring constant 7.4N/m (located o the left-hand side of the track) and compresses the spring a distance of5.3 cm from the equilibrium position. The block starts rest, is accelerated by the compressed spring, and slides across a frictionless track except for a small rough area on a horizontal section of the track. It leaves the track horizontally, flies during the air, and then strikes the ground. (g = 9.8m/s2)

a) What is the speed v of the block when it leaves the track?

b) What is the horizontal distance x the block travels in the air

c ) With what speed does the block hit the ground?
